FFMPEG PNG sequence into mkv cause "inflate returned error -3" every 600-800 frames [closed]
30 novembre 2023, par sergey9295I am new to ffmpeg. I try to use it for creating videos from png sequences. I have uncompressed pngs. All of them rgb24 format.


But during encoding process I get inflate errors. I compared PNG and video frame by frame. And video have approximately 1 dupe frame every 600-800 frames instead of the ones that should be on that places. I tried another codecs, tried to clear png's EXIF(it made things even worse), made sure that memory was enough. Doesn't matter.


The worst part is that this errors are pretty random. I encode one sequence 3 times and get 3 different sets of error-causing frames.


FFMPEG was downloaded from official site.

IMO the problem is zlib from libpng. But I don't have skills to recompile it with libspng that doesn't require zlib. Maybe there is a ffmpeg version without this error ?

Can't initialize "h264_mediacodec" for hw accelerated decoding, FFMPEG, Android
27 mars 2024, par Ramil GalinI am trying to create hw accelerated decoding on Android through JNI and following this example but, unfortunately,
avcodec_get_hw_configreturns nullptr.

I have also tried using
avcodec_find_decoder_by_name("h264_mediacodec"), also returns nullptr.

I built ffmpeg (version 4.4) using this script with the flags :


--enable-jni \
--enable-mediacodec \
--enable-decoder=h264_mediacodec \
--enable-hwaccel=h264_mediacodec \


When configuring build I saw in logs
WARNING: Option --enable-hwaccel=h264_mediacodec did not match anything, which is actually strange. FFMPEG 4.4 should support hw accelerated decoding using mediacodec.

Edit : (providing minimal reproducible example)


In the JNI method I init input context of decoder and init decoder :


void Decoder::initInputContext(
 const std::string& source,
 AVDictionary* options
 ) { // open input, and allocate format context
 if (
 avformat_open_input(
 &m_inputFormatContext,
 source.c_str(),
 NULL,
 options ? &options : nullptr
 ) < 0
 ) {
 throw FFmpegException(
 fmt::format("Decoder: Could not open source {}", source)
 );
 }
 
 // retrieve stream information
 if (avformat_find_stream_info(m_inputFormatContext, NULL) < 0) {
 throw FFmpegException(
 "Decoder: Could not find stream information"
 );
 }

 // get audio and video streams
 for (size_t i = 0; i < m_inputFormatContext->nb_streams; i++) {
 AVStream* inStream = m_inputFormatContext->streams[i];
 AVCodecParameters* inCodecpar = inStream->codecpar;
 if (
 inCodecpar->codec_type != AVMEDIA_TYPE_AUDIO &&
 inCodecpar->codec_type != AVMEDIA_TYPE_VIDEO
 ) {
 continue;
 }

 if (inCodecpar->codec_type == AVMEDIA_TYPE_VIDEO) {
 m_videoStreamIdx = i;
 m_videoStream = inStream;

 m_codecParams.videoCodecId = m_videoStream->codecpar->codec_id;
 m_codecParams.fps = static_cast<int>(av_q2d(m_videoStream->r_frame_rate) + 0.5);
 m_codecParams.clockrate = m_videoStream->time_base.den;

 spdlog::debug(
 "Decoder: fps: {}, clockrate: {}",
 m_codecParams.fps,
 m_codecParams.clockrate
 )
 ;
 }

 if (inCodecpar->codec_type == AVMEDIA_TYPE_AUDIO) {
 m_audioStreamIdx = i;
 m_audioStream = inStream;

 m_codecParams.audioCodecId = m_audioStream->codecpar->codec_id;
 m_codecParams.audioSamplerate = m_audioStream->codecpar->sample_rate;
 m_codecParams.audioChannels = m_audioStream->codecpar->channels;
 m_codecParams.audioProfile = m_audioStream->codecpar->profile;

 spdlog::debug(
 "Decoder: audio samplerate: {}, audio channels: {}, x: {}",
 m_codecParams.audioSamplerate,
 m_codecParams.audioChannels,
 m_audioStream->codecpar->channels
 )
 ;
 }
 }
 }

 void Decoder::initDecoder() {
 AVCodecParameters* videoStreamCodecParams = m_videoStream->codecpar;

 m_swsContext = sws_getContext(
 videoStreamCodecParams->width, videoStreamCodecParams->height, m_pixFormat,
 videoStreamCodecParams->width, videoStreamCodecParams->height, m_targetPixFormat,
 SWS_BICUBIC, nullptr, nullptr, nullptr);

 // find best video stream info and decoder
 int ret = av_find_best_stream(m_inputFormatContext, AVMEDIA_TYPE_VIDEO, -1, -1, &m_decoder, 0);
 if (ret < 0) {
 throw FFmpegException(
 "Decoder: Cannot find a video stream in the input file"
 );
 }

 if (!m_decoder) {
 throw FFmpegException(
 "Decoder: Can't find decoder"
 );
 }

 // search for supported HW decoder configuration
 for (size_t i = 0;; i++) {
 const AVCodecHWConfig* config = avcodec_get_hw_config(m_decoder, i);
 if (!config) {
 spdlog::error(
 "Decoder {} does not support device type {}. "
 "Will use SW decoder...",
 m_decoder->name,
 av_hwdevice_get_type_name(m_deviceType)
 );
 break;
 }

 if (
 config->methods & AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX &&
 config->device_type == m_deviceType
 ) {
 // set up pixel format for HW decoder
 g_hwPixFmt = config->pix_fmt;
 m_hwDecoderSupported = true;
 break;
 }
 }
 }
</int>

And I have
AVHWDeviceType m_deviceType{AV_HWDEVICE_TYPE_MEDIACODEC};

avcodec_get_hw_configreturns nullptr.

Any help is appreciated.

Unable to set "stream-number" pad property of mpegtsmux
8 novembre 2024, par TishSergAccroding to
gst-inspect-1.0 mpegtsmux, mpegtsmux's sink pads have writablestream-numberproperty :

...
Pad Templates:
 SINK template: 'sink_%d'

 Integer. Range: 0 - 31 Default: 0


But when I try to set it, GStreamer says there's no such property. The following listing shows I can run multi-stream pipeline without setting that property, but when I add that property it doesn't work.

I even updated GStreamer, but still no luck. I tried that because I found news saying there were updates regarding that property :


397 ### MPEG-TS improvements
 398 
 399 - mpegtsdemux gained support for
 400 - segment seeking for seamless non-flushing looping, and
 401 - synchronous KLV
 402 - mpegtsmux now
 403 - allows attaching PCR to non-PES streams
 404 - allows setting of the PES stream number for AAC audio and AVC video streams via a new “stream-number” property on the
 405 muxer sink pads. Currently, the PES stream number is hard-coded to zero for these stream types.


The syntax seems correct (pad_name::pad_prop_name on the element). I ran out of ideas about what I'm doing wrong with that property.


Broader context :


I want to set that property because I want an exact sequence of streams I mixing.


When I feed
mpegtsmuxwith two video streams and one audio stream (from capture devices) without specifying the stream numbers I get them muxed in a random sequence (checking it usingffprobe). Sometimes they are in the desired sequence, but sometimes they aren't. The worst case is when the audio stream is the first stream in the file, so video players get mad when trying to play such.tsfile. I have to remux such files using-mapkey offfmpeg. If I could set exact stream indices inmpegtsmux(not to be confused with stream PID) I could avoid analyzing actual stream layout and remuxing.

Example of the real layout of the streams (
ffprobeoutput) :

Input #0, mpegts, from '████████████████████████████████████████':

You can see 3 streams :


- 

- FullHD video with PID 0x41 (defined by me as
mpegtsmux0.sink_65) has index 2 while I want it to be 0 - PAL video with PID 0x42 (defined by me as
mpegtsmux0.sink_66) has index 0 while I want it to be 1 - Audio with PID 0x4b (defined by me as
mpegtsmux0.sink_75) has index 1 while I want it to be 2
