ffmpeg recognises MXF dv but won't encode to h264
6 août 2017, par 3pointeditI have a DV file encoded as an MXF that I want to transcode to h264. Running ffmpeg against the file it reads ok and understands the stream but won’t write the h264 file. It seems to get all the streams correct and I can confirm the attributes of video and audio streams.
I just don’t understand why it won’t encode ? I tried to force a Decoder with -f dv but it complained that the source header was incorrect.

FFmpeg unexpected behavior using -loop flag
7 décembre 2020, par all jazzDear hackers of the world !


I've been trying to use the beloved FFmpeg library to create a video from an image loop and audio using the famous Docker FFmpeg image, but it has been driving me crazy not producing the expected results (the results that I get when I run the ffmpeg command with the equivalent version on my Macbook).


Here is the command :


docker run -v $(pwd):$(pwd) -w $(pwd) jrottenberg/ffmpeg:4.3-alpine \
 -y \
 -stats \
 -loop 1 -i files/image.jpg \
 -i files/a.mp3 \
 -c:v libx265 -pix_fmt yuv420p10 \
 -c:a aac \
 -movflags +faststart \
 -shortest \
 -f mp4 test.mp4


It should create a test.mp4 with the provided audio and image that is ready to be uploaded to the unfortunate Youtube.


When I do this, the video seems to be lacking moov atoms (if I try to analyse it). Strangely enough, if I run this two times using the Docker image (overriding the same file), the video file will magically start to work.


I also tried using different ffmpeg os images and versions. It seems that ffmpeg docummentation and code repo could also benefit from some care and love.


What else I could do to get this fixed ?


Here is the output from the console :


-y \
 -stats \
 -loop 1 -i files/image.jpg \
 -i files/a.mp3 \
 -c:v libx265 -pix_fmt yuv420p10 \
 -c:a aac \
 -movflags +faststart \
 -shortest \
 -f mp4 test30.mp4
