Adding HEVC reference decoder to ffmpeg framework
4 mars 2014, par ZaxI have a tweaked HM reference code of HEVC Decoder based on my requirements. I also know that
FFMPEG version 2.1
onwards supports HEVC. But its a necessity for me to integrate my modified HM code.Hence I have gone through the post :
http://wiki.multimedia.cx/index.php?title=FFmpeg_codec_howto
According to this post, I need to define some functions that are needed to add a new decoder support to FFMPEG framework.
The structure is :
typedef struct AVCodec
I have defined a structure as shown below :
AVCodec HMHEVC_decoder =
{
.name = "hmhevc",
.type = AVMEDIA_TYPE_VIDEO,
.id = AV_CODEC_ID_HMHEVC,
.init = hmhevc_decode_init,
.close = hmhevc_decode_close,
.decode = hmhevc_decode_frame,
};However, looking at the other examples, I feel I have to add another variable like :
.priv_data_size = sizeof(HEVCContext),
But the problem is that I don't have any such context. So in case I don't define this, what are the things that FFMPEG framework wont provide my decoder ?
Also is definition of this private data context compulsary ?
What are the other fields that have to be compulsorily defined ?
My main intention is that
FFPLAY
should be able to play the decoded frame. -
Input seeking for frame at specified timestamp with Py-AV
9 décembre 2019, par neonScarecrowI have a project already using Py-AV and am trying to replicate a specific ffmpeg command. The goal is to get a frame roughly around the specified timestamp.
Here’s the ffmpeg commmand :
https://trac.ffmpeg.org/wiki/Seekingffmpeg -ss 14 -i https://some_url.mp4 -frames:v 1 frame_at_14_seconds.jpg
Here’s my code :
#return one frame around 14 seconds into the movie
target_sec = 14
container = av.open('https://some_url.mp4', 'r')
container.streams.video[0].thread_type = 'AUTO'
video_stream = next(s for s in container.streams if s.type == 'video')
time_base = float(video_stream.time_base)
target_timestamp = int(target_sec / time_base) + video_stream.start_time
video_stream.seek(target_timestamp)
for frame in container.decode(video_stream):
frame.to_image().save('frame_at_14_seconds.jpg')
breakAdditionally, I have found any documentation about this, but does anyone know if either command (ffmpeg/av.open) is downloading the entire file to a tmp file behind the scenes. I’m looking for a less memory-intensive way to read a frame for every second in an up to 60 second video.

Why is my DSharpPlus Slash Command not playing my desired sound using FFMPEG in C# ?

playing the playsound slash command but wasn't expecting it to not play the mp3 file.


everything else worked fine except when it transmits the sound it doesn't play it.
