How to detect added scenes in Director's Cut Edition of movie? - B Lolo Newest 'ffmpeg' Questions - Stack Overflow

Using libavformat to mux H.264 frames into RTP - DanielB6 Newest 'ffmpeg' Questions - Stack Overflow

I have an encoder that produces a series of H.264 I-frames and P-frames. I'm trying to use libavformat to mux and transmit these frames over RTP, but I'm stuck. My program sends RTP data, but the RTP timestamp increments by 1 each successive frame, instead of 90000/fps. It also doesn't look like it's doing the proper framing for H.264 NAL, since I can't decode the stream as H.264 in Wireshark. I suspect that I'm not setting up the codec information properly, but it appears in many places in the output format context, so it's unclear what exactly needs to be setup. The examples seem to (...)

ffmpeg concat and preserve metadata streams - Andrew Newest 'ffmpeg' Questions - Stack Overflow

I'm trying to concat multiple files that are the result of a GoPro Hero6 splitting movies to avoid the FAT 4GB limit. ffmpeg works great for this purpose but I need the telemetry data that is encoded in the metadata streams, and ffmpeg by default doesn't seem to preserve this.

How to find a "safe" point for -SS using FFMPEG to avoid breaking A/V sync? - user3144514 Newest 'ffmpeg' Questions - Stack Overflow

I need to find a way to cut video using -SS without breaking the audio/video sync. Once in a while it works perfectly fine, but most of the time the audio falls slightly out of synch. Clearly there is something akin to a keyframe for audio, but I do not know how to find them. The problem happens when using -SS in conjunction with Any specification for a codec, including -c copy. For my purposes, I can't lose quality so those are necessary. ffmpeg -i src.mp4 -ss 1:00 -t 30 -c copy result.mp4 tends to break the sync. ffmpeg -i src.mpr -ss 1:00 -t 30 result.mp4 produces matching a/v but (...)

How can I install ffmpeg if I'm using Cloud Foundry and a python buildpack - david balague Newest 'ffmpeg' Questions - Stack Overflow

I'm writing a python application which uses pydub and want to run it in the cloud, I'm using IBM's ibmcloud Cloud Foundry implementation to deploy the application. pydub requires access to ffmpeg.

dump_extra: Don't add extradata if it already exists - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

dump_extra: Don't add extradata if it already exists The dump_extra bitstream filter currently simply adds the extradata to the packets indicated by the user without checking whether said extradata already exists in the packets. Besides wasting space duplicated extradata in the same packet/access unit is also forbidden for some codecs, e.g. MPEG-2. This check has been added to be able to use the mpeg2_qsv encoder (which only adds the sequence headers to the first packet) in broadcast scenarios where repeating sequence headers are required. The check used here is not perfect: E.g. (...)

avcodec/dvbsub: add support for Display Definition Segment to DVB Subtitle encoder - Jernej Fijacko git.videolan.org Git - ffmpeg.git/rss log

avcodec/dvbsub: add support for Display Definition Segment to DVB Subtitle encoder Current version of dvbsub encoder doesn't support HD DVB subtitles. The high resolution bitmaps are muxed into the stream but without the DDS (display definition segment) the players asume that the DVB subtitles are in SD (720x576) resolution which causes them to either render the subtitles too large and misplaced or don't render them at all. By including the DDS as defined in section 7.7.1 of ETSI EN 300 743 (V1.3.1) this problem is fixed. 7.2.1 Display definition segment The display definition for (...)

ffmpeg Reduce frame rate - Chieron Newest 'ffmpeg' Questions - Stack Overflow

I am trying to convert h264 vids to h265. Some of the vids are 50fps and seem to have a lot of duplicate frames(100000+). I guess these are 25fps vids and somehow they have every frame duplicated. ffmpeg is not dropping the frames it seems and so I guess this is wasting space(although I'd hope very little but it's probably not optimal). I'd like to fix this though. is there a way to set the frame rate to 30, say(-r 30) and have ffmpeg correctly keep everything in sync(audio aligned properly) and not have any real issues? this might require interpolation and all that but I definitely do (...)

truehd_core: Switch to in-place modifications - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

truehd_core: Switch to in-place modifications The truehd_core bitstream filter decreases the sizes of the major_sync_info structure (if present), of the substream_directory and of the substreams themselves. As a consequence, there is enough space available in front of the actual substream data for the new header, so that one only needs to modify the header in front of the actual data (which apart from shrinking is left untouched) and the packet's size and buffer pointer (after having made sure that the packet is writable). This and switching to bsf_get_packet_ref also removed the need (...)

truehd_core: Use byte offsets instead of bit offsets Words of 16 bit are the unit for TrueHD's size and offset fields; in particular the sizes of the high-level structures of TrueHD are always a multiple of a byte; yet truehd_core unnecessarily used bit offsets at several places.

The loop counter of the substream_directory loop is always less than the number of substreams, yet within the loop it is checked whether it is less than FFMIN(3, s->hdr.num_substreams), although the check for < 3 would suffice. 2. In case the packet is a major sync packet, the last two bytes of the major sync structure were initialized to 0xff and then immediately overwritten afterwards without ever making use of the values just set. 3. When updating the parity_nibble during writing the new substream_directory, the parity_nibble is updated (...)

truehd_core: Disable 16-channel presentation - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

truehd_core: Disable 16-channel presentation The most serious bit of the substream_info header field (in a mayor sync packet) indicates whether a 16-channel presentation is present in the bitstream. If set, the extended_substream_info header field contains information about the 16-channel presentation. This presentation always uses substream 3, a substream that is discarded by truehd_core. So substream_info needs to be changed to no longer indicate the presence of a 16-channel presentation in order for truehd_core's output to be consistent. This is implemented in this commit.

Using ffmpeg or ffprobe to get the pixel bit depth of a video - jippyjoe4 Newest 'ffmpeg' Questions - Stack Overflow

Is it possible to use ffprobe or ffmpeg to figure out the bit depth of a video file? I specifically want to know how many bits per channel (bpc) my video is. 8 is typical, but some fancier codecs can use higher bit depths, and I'm not sure how to obtain this information using ffprobe, or if it's even possible. Specifically, I have videos encoded using the AVC-Intra Class 100 1080p 59.94 fps codec, but I'm not sure if ffprobe can obtain the bit depth from that kind of file or not. If so, how would you do (...)

I'm trying to programmatically export a series of thumbnail images (one image per-second) I'm not worried about the actual footage conversion and image file creation. My interest is in how would it be better to capture a valid 1 fps frame. (with no artifacts) This is possible using FFmpeg's command line like this: ffmpeg -i test.mp4 -vf fps=1 out%d.png So while looking at the FFmpeg's source code I've noticed that it's using a thing called filters. While filters can do a lot of cool stuff, I'm not sure if using those wouldn't be too much of an overhead for a relatively simple task like (...)

Initializing an output file for muxing mkv with FFmpeg - MPM Newest 'ffmpeg' Questions - Stack Overflow

I'm a first time user of ffmpeg and I'm having trouble with initializing an output file for mkv muxing. I followed the description on the middle of this page but it doesn't work. When I call the avformat_write_header() function it returns the error code -1094995529, which means: Invalid data found when processing input. When I allocate the output context to mp4 format (I use in both cases the avformat_alloc_output_context2) I don't get this error, and it sucessfully writes the header. I tried to analyze the code of this example but I couldn't figure out what the problem is (I also tried (...) -- on the middle of this page, the code of this example
